WellChrom Spectro - Photometer K - 2501

The WellChrom Spectro Photometer K-2501 is equipped with a polychromator which is positioned with high precision mechanics for selection of the detection wavelength. It allows reproducible measurements in the whole wavelength range. Time-programmed wavelength switch can be performed during data acquisition so that the best wavelength for every peak can be chosen.

Additionally, stopped flow spectra scan is supported. This is a valuable feature during method development. The K-2501 is a versatile yet robust, modestly priced, high performance detector that meets most requirements in UV-detection.
